What is variable frequency drive (VFD)?

Variable Frequency Drive (VFD) is a technique often used to achieve the adjustable speed drive of AC motors to control its speed as well as torque. Before going into the details of variable frequency drive system, let us take a look at the need for variable speed operation of an electric motor.

What is a variable frequency drive system?

A Variable Frequency Drive system is also known as Adjustable Frequency Drive (AFD) or Variable Speed Drive (VSD) or Variable Voltage Variable Frequency (VVVF) Drive. It is a simple device that controls the voltage and frequency of the input power of a motor and therefore controls speed of the motor as well as the system being driven by the motor.

What does VFD stand for?

Sensorless vector, closed loop control variable frequency dual voltage drive with variable torque ratings. Part No: 2124098 Categories: General Purpose Drives, Variable Frequency Drives (VFDs)

What is the global variable frequency drive (VFD) market?

The global variable frequency drive (VFD) market is slated to experience healthy growth over the coming years. These drives are emerging as an integral part of several machine markets globally both small- and large-scale. They are used in applications ranging from small devices to large compressors.
